DISPLAY SIGN AND MEANS FOR MOUNTING THE SAME.

YApplication filed January 13, 1926. Serial No. 80,893.

My invention relates to display signs and means for mounting the same. In its more specific aspect, the invention is concerned with a small advertising sign so constructed that it can be quickly and easily clamped to the top of the conventional cash register or checking register. By providing Vthe signs with clamping means for attachment to cash registers',y the sign has a ready and available support for mounting in practically all shops, stores and restaurants. When thus mounted on the register the sign is attention-getting because of its prominent position and its proximity to the indicating ligures on the register.

It is one ofthe principal objects of the present invention to provide a simple and effective construction of sign mounting means and clamping devices therefor, which clamping devices will hold the sign securely on the register, and which will also be adjustable for adapting the unit for mounting on diderent types and sizes of registers.

It is a further object of the invention to provide fastening elements for these clamping devices which will prevent releasing of thefclamping devices, at least with the tools ordinarily at hand. This is to prevent the Shop keeper, after accepting the sign as a gratuity, from removing it before it has ful, lled its advertising function. Referring to the accompanying drawing illustrating my invention:

Figure 1 is a perspective view of a typical cash or checking register showing vmy im* proved sign mounted thereon.

Figure 2`is a fragmentary sectional view through one of the supporting standards and its associated clamping devices.

Figure 3 is a side elevational view of the standard and clamping means.

Figures 4 and 5 are detail views of one type of special screw Vfor the clamping devices.

Figure 6 is a fragmentary sectional view illustrating another type of screw.

Figure 7 is a view generally similar to Figure 2 illustrating a modified construction of clamping device, and Y Figure 8 is a transverse sectional view taken on the line 8 8 of Figure 7.

The types of cash or checking registers now in most prevalent use are typied by the register illustrated in Figure 1, these registers generally having a dat top surface 12 consisting of a pane of glass or a flatmetal plate. rlhe present sign has been devised for mounting on this flat upper surface 12. In the usual construction this flat upper plate 12 projects slightly along its front and rear edges as indicated at 13-13 in Figure 2, and to those projecting ledges the sign can be securely clamped.

The sign comprises a plate or panel 14 on which appears the subject matter of the advertisement, this plate or panel being glass, metal, or any other preferred materiel.- Supporting the plate at its ends are two uprights or standards 15-15- As shown in Figures 2 and 3, the inner face of each upright is formed with a slot or groove 16 into which projects the ends of the sign panel.

Each upright or standard 15 has an arrangement of clamping devices whereby it can be fastened in erect position on the top surface 12 of the register. In the preferred embodiment these clamping devices comprise a clamping foot or rest 18 which is formed integral with the lower end of each upright 15, and a cooperating clamping section 19. Each clamping foot 18 is foimed with a clamping hook 21 adapted to engage over the projecting edge 13 of the top surface 12. The separate clamping section 19 has a similar clamping hook 22 for engaging over the projecting edge 13 on the opposite side of the plate 12. These two clamping devices 18 and 19 have an extensive area of contact with the top surface 12 and afford a firm support for each upright.

The clamping portion 18 has a threaded bore 23 tapped into the inner end thereof. The other clamping member 19 has an apertured ear 24 extending upwardly from its inner end. A clamping screw 25 passes through this apertured ear and screws into the threaded bore 23 for drawing the two clamping sections into iirin engagement with the edges of the top plate 12. -The clamping screw 25 gives a considerable latitude of adjustment between the two cooperating clamp sections whereby the device can be clamped to top surfaces 12 of widely varying widths. When drawn together Linder the tension of the clamp screws, the clamping sections of both uprights rigidly hold the uprights against sliding movement on the top plate or any other movement by which the sign might be removed.

The sign is generally a gratuity to the shop keeper and it is desirable to prevent his removing the sign 'any time at'hisfpleasure. To this end the invention embodiesimf 1n the lclamping screws' 25" cesses 27 in the clampinglugs 245 whereby only the'iend of the 'screw head lsaccessibl'e' after the clamps have been rdrawn up tight; Each screw head has a keriz therein `one side of which, on opposite sides ot' the head; :1re milled or cut away. This leaves abrupt shoulders 29 facing" in one directionl by which the'V screw can be driven :lionie'by the ordinary screw driver to draw the clamps together. The cut away sides ot the kerf leave sloping` "surfaces 31 with which the bit ot the screw driver can have no effectual en; gagement. Thusaiter the screwhas been driven home to hold the clamps in firm clamping engagement on the cash register, the screw can not be removed, at least by the ordinary screw driver.

Another t'orin oit clamping" screw is illustrated in=Figure 6. In this type, the screw has a spanner'head 33 pre ierably olicylindrical form, having the Spanner sockets 34' entering this cylindrical head radially. This type ot screw can not be released except throughv the'use of a special spanner wrench of proper size to engage these screw holes.

In Figures 7 and8` I have 'illustrateda' modiiiedl construction of clamping means wherein one Clamp' sectionA aiiords guiding" support lfor the other clampsection".` The lclampsectionlS' has a proj'ectingendpor- 18 andserws'in-to v`a Athreaded 'bore 4l' in the" other clanfp section, Valthough-this arrange! ment may be reversed ifdesired. This screw' may be"` provided 4vwitha one-way kerf such as is shown in Figures 4 and 5 or may be' providedv with'i a Spanner 'head such- 'asf is' shown 4in Figure' 6." f

Having tlius described my inventiony what'I'claim as-new and ldesire to'rsecure Letters Patent ofthe lUnitedStates is:

In an advertising device, a pair'L of in-" tegral standards each having a fiat foot at its base,' said 'standardshaving longitudinal slots in their opposed sides, with an-adverl tising plate adapted to vbe receivedfin said slots'7 said foot having a guide formed therein, a clamping lugonsaidlfoot, a'second clamping member' slidingin said guide;`lr and screw ni'eans' enclosed insaid foot tor' actuating said clamping member toward said lug'7 said screw'mean's havingakerf without engaging shoulders'to unsorewthe saine.
